Suspension Rubber Buffer Bump Stop impermeability and insulation

- Mar 19, 2019-

Suspension Rubber Buffer Bump Stop is a device that can limit the maximum deformation of the suspension. It reduces the direct impact of the axle on the frame and prevents excessive deformation of the elastic component. Suspension rubber bumper stop is composed of rubber blocks, steel plates and bolts. Some buffer blocks are made of porous polyurethane and are hollow inside.


One of the advantages of the suspension rubber bump bump stop is that it has a unique water impermeability. The Pu rigid foam used in the polyurethane buffer block is a structurally dense microcellular foam with a closed cell ratio of 92% or more. At that time, it will have a relatively smooth self-skinning, and at the same time it is a relatively good impervious material. Direct spraying technology will be used in the construction.


The Pu hard foam layer in the suspension rubber bump is not integrated with the seam, which will form a complete impermeability, and then it will fundamentally eliminate the possibility that the roof water will penetrate from the seam. The Pu hard foam layer can be firmly adhered to the base layer, and its bonding strength will exceed the tear strength of the foam itself. At this time, the Pu hard foam and the base layer are integrated, and delamination is not easy to occur. Water is prevented from penetrating between layers.


Suspension rubber bumper bump stop has better insulation and its better insulation performance, and the energy saving effect of this equipment will be more significant. Since the thermal conductivity of Pu hard foam is relatively low, the thermal insulation and its thermal insulation effect are not comparable to any other roof insulation materials.
